If you demand high performance from your home theater system, you need surround speakers that provide great sound and exceptional flexibility. The FXi3 dipole/bipole speakers deliver subtle, detailed surround effects for stellar home theater. You'll enjoy a great mix of direct and indirect sound, thanks to the 45° angled driver arrays. Featuring the latest generation of Dynamic Balance® drivers, the FXi3 features a 1" silk/polymer dome tweeter and a 5-1/4" woofer mounted on one baffle, and a second matching tweeter on the other. Multichannel movies and music really shine! A dipole/bipole switch changes the phase relationship between driver arrays for lots of placement flexibility. Depending on your setup, you can have the separate tweeter firing in phase with the other drivers (bipole), or out of phase (dipole). The bipole setting is great for speakers placed behind your listening position, and provides clear, directional sound, while dipole usage is ideal for placement to the side of your listening position and results in a more diffuse soundfield. Also includes a keyhole slot for wall-mounting.
